With kernel based dnotify you shouldn't have to do anything,
the smbd should get signalled once the file is gone causing
it to notify the client.

Unfortunately there's no debug messages in the kernel
inotify handler (that's an oversight, I'll add one once
I'm back at work tomorrow). Can you add one (in the
function inotify_handler() in smbd/notify_inotify.c and
see if it gets triggered appropriately ?
